Storage

3. Storage
If it needs to be stored, the equipment must be placed on
dry ground or on top of damp-proof insulating material, still
in its original packaging.
Figure 3.1. Storage
Storage must always be INDOORS, with the following
conditions recommended:
1. Ambient air temperature should not exceed 40°C
and its mean value, measured in a period of 24 hours,
should not exceed 35°C.
2. The ambient air temperature should not drop below
- 5°C. There are also cubicles with storage temperature
up to -40°C.
3. The switchgear must be protected from direct solar
radiation.
4. Altitude, both in transport and in storage, must not
exceed 2000 m.
5. The environmental air must not have any significant
contamination from dust, smoke, corrosive and/or
inflammable gases, vapours or salt.
6. The switchgear must be protected from the rain, and
the humidity conditions should be as follows:
a. The mean relative humidity value, measured over a
period of 24 hours, must not exceed 95%.

cgmcosmos: Medium voltage cubicles with full insulation
in SF gas up to 24 kV in accordance with IEC Standard
6
After prolonged storage, clean all the insulating parts
carefully before commissioning the equipment. The
enclosure should be cleaned with a clean, dry lint-free cloth.
b. The mean water vapour pressure value, measured in
a period of 24 hours, must not exceed 2.2 kPa.
c. The mean relative humidity value, measured over a
period of one month, must not exceed 90%.
d. The mean water vapour pressure value, measured
in a period of one month, must not exceed 1.8 kPa.
7. During transport, vibrations caused by external factors
or seismic movements must be insignificant.
Any other conditions must be notified beforehand,
since the equipment must be factory-adjusted to
the environmental pressure at the final destination
or during transport. Otherwise, the pressure gauge
needle may indicate an incorrect value, even if the
equipment's internal gas pressure is correct.
